sdlxGetCurrentRenderOutputSize function render

({int h, int w})? sdlxGetCurrentRenderOutputSize(Pointer<SdlRenderer> renderer)

Get the current output size in pixels of a rendering context.

If a rendering target is active, this will return the size of the rendering target in pixels, otherwise return the value of SDL_GetRenderOutputSize().

Rendering target or not, the output will be adjusted by the current logical presentation state, dictated by SDL_SetRenderLogicalPresentation().

\param renderer the rendering context. \param w a pointer filled in with the current width. \param h a pointer filled in with the current height. \returns true on success or false on failure; call SDL_GetError() for more information.

\threadsafety This function should only be called on the main thread.

\since This function is available since SDL 3.2.0.

Implementation

  Pointer<SdlRenderer> renderer,
) => ffi.using((arena) {
  final wPointer = arena<Int32>();
  final hPointer = arena<Int32>();

  final result = sdlGetCurrentRenderOutputSize(renderer, wPointer, hPointer);

  if (!result) {
    return null;
  }

  return (w: wPointer.value, h: hPointer.value);
});
